Synopsis:  

This routine generates comparison plots from data files generated by
either cloudy_pl_loop or python_pl_loop. 


Command line usage (if any):

	usage: cloudy_pl_loop *run1* *run2*.
		the expected file names are 

		cl_hydrogen_*run1*.dat
or		py_hydrogen_*run1*.dat.

The cl or py prefix tells the code which type of data we have.
